  • Build your own awesome, wearable mechanical hand that you operate with your own fingers.
  • No motors, no batteries — just the power of air pressure, water, and your own hands!
  • Hydraulic pistons enable the mechanical fingers to open and close and grip objects with enough force to lift them. Every finger joint can be adjusted to different angles for precision movement.
  • Three configurations: right hand, left hand, and claw-like; adjustable to fit virtually any human hand.
  • Learn how pneumatic and hydraulic systems are used in industrial robots such as automobile components..2021 The Toy Association's STEAM Toy Of The Year Winner
  • Explore hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand! Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items anything with reach! The hand can be configured in three ways left hand, right hand, and claw-like, with the thumb in the center and can be adjusted to fit virtually all hand sizes.

    5.0 out of 5 stars Perfect STEM Gift: Fun and Educational Mega Cyborg Hand Kit!

    L.C. · January 3, 2025

    I bought the Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit as a Christmas gift for my 9-year-old son, and it was a huge hit! From the moment he opened it, he was excited to dive into the building process.The instructions were clear and easy for him to follow, and he managed to assemble it mostly on his own, with just a little guidance. Watching him figure out how each piece fit together and seeing his pride in completing it was priceless. The kit provides a fantastic hands-on learning experience, teaching mechanical concepts and the basics of hydraulics in a fun and engaging way.Once assembled, the cyborg hand is incredibly cool. It fits comfortably, works smoothly, and my son has been having a blast testing its capabilities, like picking up objects or pretending he's a robot. The fact that it’s adjustable for different hand sizes means he’ll be able to use it for a long time.This STEM kit is not only entertaining but also educational, sparking curiosity about engineering and science. I highly recommend it for any kid who loves to build, tinker, and explore how things work. It's a gift that keeps on giving!

    5.0 out of 5 stars Takes a while to assemble but I enjoyed it.

    Fun to build (if you're into models). Works well once assembled.

    4.0 out of 5 stars Good product, most kids will need some help in assembling it. But it works if you get to the end!

    E.V.H. · September 8, 2025

    Bought this twice - once as a gift for another kid and then again for my son's birthday. It is pretty cool and functional - not really easy to put together. My mechanically-inclined ten-year old was able to figure out most of it on his own, though some sections were a little confusing and it does take a bit of dexterity to get some of the pieces figured out. Instructions are mostly straightforward, but you do really need to ensure you read them correctly (mostly diagrams and numbers, not words). Overall a worthwhile gift - but plan on providing some not insignificant adult supervision to help build it. BTW beware not to accidentally throw away the hydraulic oil! It looks like a dessicant pack, but it is not, and you need it! Finally hand is capable of picking up things like cups of water, etc.

    5.0 out of 5 stars 14 yr old loved it. Needed family's craft knife, small head screw driver, and cutting board.

    14 yr old grandchild was ecstatic when they opened this present. They are an experienced Lego builder, but hadn't run across a project where the pieces had to be cut apart. Each color was cast in a sheet, with connecting thin plastic. For instance, all the black pieces were connected together. Same with the blue, yellow and white. Some other parts, like the hydraulic cylinders and small screws, came in plastic bags. Following the diagrams, they cut loose each piece as it was needed, and not before. A parent emphasized that it was important not to over tighten the screws.For a somewhat younger person, an older one could act as an assistant in separating the parts as needed. Assembling the hand is a good exercise in focus and patience in following the steps. It was fun for the 14 year old to take time and tackle this challenge. It took him something like 4 hours. Taking breaks reduces stress for those susceptible.The hand is adjustable in several ways, including being able to attach the fingers in different places. Grandchild had fun testing the hand's functions and abilities.

    My 5 year old and 12 year old really enjoyed putting these together. Little tough for my 5 year old but with help of siblings he had a blast.

    5.0 out of 5 stars Very cool toy - even better company.

    R.H. · May 1, 2025

    So many good things to say about this.#1 - Over and above product support. We lost two of the screws in the kit (as you do). Reached out, expecting little help and lots of shipping fees. Nope. Immediately they responded that they are shipping parts to us for free.#2 - Actually very cool product. It’s fun to build, comes with bonus (fun but educational) content about how hydraulics work (that our son actually read and enjoyed).He loved building it and has been picking up EVERYTHING with his cyborg hand.He’s twelve and loves video games but this kept his interest over weeks of building and playing.Big win.

    5.0 out of 5 stars Best for 15-16 year olds-5 stars for end product. 4 stars for being a challenge to assemble.

    L. · July 11, 2024

    After reading the reviews on difficulty level I decided to get this for my 16 year old. He is very good with putting things together and this took him about 6 hours to assemble over a few days. He (gently) used a power drill because the screws were too difficult to do manually. It is a great gift for an older kid that likes to build but would not recommend it for the ages listed in the description. He enjoyed it, it was challenging enough without being overly frustrating and not so easy that he was done with it in no time. It is a very cool hand and works really well!

    The Mega Cyborg Hand kit is a fun and educational STEM project that my child really enjoyed building. The hydraulic system is a great way to introduce kids to basic engineering and mechanics, and the instructions were fairly clear. However, some parts were a bit flimsy and didn’t fit together as well as expected, which caused a bit of frustration during assembly. Also, the hand is quite large and not very comfortable to wear for extended periods, even with the adjustable straps. Overall, it’s a decent kit for older kids who are patient and enjoy building things, but it could use some improvements in design and durability.

    Damaged box and opened seal

    While the parts in the box is all complete, the box is dented and the seal is broken. Meant to be a gift for a little boy. Lesson learnt to buy toys from physical stores in the future

    Shipment issue

    K. · May 14, 2024

    The product looks amazing with very very detailed instruction inside. However, the box was delivered without wrapping, no Bolo bag, no Bolo box. The box is damaged and does not look like a new one. The shipment sticker was put directly on the box with the product. This is a gift and it took me a while to remove the sticker. Consider another seller of this product.

    Un gran regalo

    Me parece un excelente producto. Dudé para comprarlo al leer algunos comentarios negativos, pero, ahora pienso que no es exacto lo que comentan. Por eso mi interés en compartir nuestra experiencia, a mi hijo le encantó de regalo de cumpleaños, a sus 11 años, prácticamente él y su hermano lo armaron solos. Sí, le compré unas tijeras como las recomendadas y una pequeña lija que fueron muy útiles; el desarmador de cruz ya lo teníamos en casa. Yo busqué un tutorial en YouTube, sin embargo, mi hijo prefirió seguir el instructivo impreso incluido, ambos fueron de mucha utilidad. El material es plástico de muy buena calidad, tiene excelentes acabados, todo está perfectamente marcado para no equivocar las piezas. Les tomó más de 4 horas ensamblarlo, los mantuvo interesados y activos. Fue muy intuitivo su uso y muy fácil de entenderlo. 100% recomendado.

    Awesome toy- interactive.

    This was amazing to play with and a big hit with my 8 yr old. A year later and he still plays with it.
